1, 4-DIOXANE
CAS # 123-91-1
DESCRIPTION
1, 4-Dioxane is a
colorless, highly flammable hygroscopic liquid with a mild, sweet ether-like
odor. It is infinitely soluble in water and most organic solvents (i.e.,
alcohol, ether, acetone, benzene, acetic acid). It is also miscible with
aromatic hydrocarbons and oils. 1, 4-Dioxane is stable, incompatible with
oxidizing agents, oxygen, halogens, reducing agents, moisture.

APPLICATION
SOLVENT
1,
4-Dioxane is used primarily as a solvent in paints, varnishes, lacquers,
cosmetics, deodorants, cleaning and detergent preparations, and in liquid
scintillation counting mediums. There is also the potential for use it as a
solvent in the processing of crude petroleum, petroleum refining,
petrochemicals, pulp and paper, explosives, commercial printing,
electroplating/polishing, pesticides, dyes, fibers, pharmaceuticals, veterinary
drugs, adhesives, semiconductors, electronic components, photographic equipment,
magnetic recording media, polymers, plastics, rubber manufacture, organic and
inorganic chemical manufacture.
In the laboratory, 1, 4-dioxane is useful as a cryoscopy solvent for molecular mass determinations and as a stable reaction medium solvent in chemical synthesis, research and analysis. Because of its lower toxicity, it is sometimes substituted with tetrahydrofuran (THF) in some processes
STABILIZER
1, 4-Dioxane often has
been used with chlorinated solvents or volatile organic compounds (VOCs). It is
primarily used as a stabilizer and corrosion inhibitor for 1, 1,
1-trichloroethane for storage and transport in aluminum containers.
WETTING AND DISPERSING AGENT
1, 4-Dioxane is also used as a wetting and dispersing agent in textile processing
Other uses:
·
Preparation of histological sections for
microscopic examination.
·
Extracting agent.
·
Analytical reagent for the laboratory use
